Even though teaching global warming science has been part of UK school curriculum since the mid 90s, the head government advisor reviewing national education plans says schools should "get back to the science in science." Commenting that prominent scientific issues "changed dramatically" from year to year, Tim Oates said, "the national curriculum shouldn't ever try to keep up with them, otherwise it would keep changing" and that "it's really important that children think through the social application of science, but the precise topics do not have to be specified by the state."
